Okay, now ido enters into the loop again...

I added your code (as is) to the init file you gave upthread, and I see 
the exact same behavior in Emacs 27 and 28.  When the activation of 
test-mode is made conditional to (minibufferp), I again see the exact same 
behavior in Emacs 27 and 28.

And with both Emacs 27 and 28, minor-mode-overriding-map-alist is nil 
after ido-resurrect-keybinding.
